DAVID EDWARD DAVIES, OF STOOKWELL, ENGLAND.

ENVELOP.

Application filed September To all whom it may concerm Be it known that 1, DAVID EDWARD DAVIES, a-subject of the King of Great Britain and Ireland, residing at Stockwell, in the county of Surrey, England, have invented new and useful Improvements in or' Connected with Envelope, of, which the following is a specification.

This invention relates to improvements in or in connection with. envelope inanufactured in what may be termed chains, each envelop forming a link-of the chain and being 'connected to its ad acent links in a readily detachable manner. Envelo s so linked upare as is well known specia ly' suitable for employment in connection with type writing machines especially when a large number of envelope have to be addressed, as the first envelop of the chain can be inserted and adjusted in the machine and then addressed, the envelope forming the remainder or a part of the chain being fed forward one by one to theprinting point. Bylthis means the insertion and-adjustment of each envelop to .and- 9 to Figs. 3 and .4.

be addressed is obviated for it will be under stood that after the first envelop is inserted and-adjusted the remaining envelops of the chain will, as the platen is rotated, be fed forward to the printing point automatically and with little, if any, further adjustment.

Referring now to the accompanying draW-.

ings, Figure 1 shows one form of blank in accordance with this invention. Fig. 2

shows the blank'partly folded. Fig. 3 shows a blank of a shape diflering slightly from that shown in Fig. 1. Fig. l isa similar view to Fig. 2 of the blank shown in Fig. 3. .Fig. 5 shows blanks of the shapes shown in Figs. 1 and 3' and. folded as shown in Figs. 2 and 4. joined together so as to form what is herein called a chain of envelops. Figs. 6 and"? are similar views to Figs. 1 and 2, and Figs. 8 Figs. 10, 11 and 12 are views of a further modification and Fig. 13 is a similar view to Fig. 5 showing the last modification in completed form.

According .to the arrangement shown in Figs. ,1 to5 inclusive the blanks are cut as irregular polygons of such shape that when the blank is partly folded as shown in Fig. 2' .it forms the front or address bearing part Eatented July 14-, ieoe.

it, 1906. Serial No; seem.

shown in Fig. 5.

The blank has, at what may be regarded as its upper art, a rectangular, or practi- Cally rectangular, portion that is divided into two unequal parts 2*, 2 by a line of perforations or incisions 3. The part 2" which. is above the lineof perforations or incisions 3 and is the larger of the two parts, forms a main portion namely, in the present form of the invention, the back of an adjacent envelop in the chainof envelops (see Fig. 5),

.and the part 2 forms the closing-flap of the envelop-the. front or address bearing part and the side and bottom flaps of which are inade in one therewith. Below the rectangular, or ractically rectangular portion, is a part 4 w iich, when the blank is folded, will form the front or address bearing part of the envelop. The part 4 has on three of its sides, fla s or extensions 5, 6, 7 which, when the blan is folded, extend toward the center of the part 4. These flaps or extensions 5, 6, 7 are guinnied along their inwardly extending edges and the part 2 of the rec tangular, or practically rectangular, portion of another blank is secured thereto: the inwardly extending edges of the side flaps or. extensions 5, 6 are so guinined that the upper or under surface of the part 2- oi the other blank can. be secured thereto. Fig. 5 at A and B illustrates the two ways in which the side flaps or extensions 5, 6 and the part 2 can" be united. The part 2 is of such a size that it will formv the back of an envelop (see .Fig. 5). and it is 'so placed that the line of perforations or incisions 3 will coincide with "or come on the line of fold of the bottom lie. 7 of'the blank to which the part 2 is to e attached. It will thus be understood. that a chain of envelope will be formed when the larger of the two portions of the u per part of one blank is attached to the laps, side and bottom, of the part of another blank that forms the front or address bearing side of another envelop and that the envelops can "be readily separated "the one from the other by tearing along the line of perforations.

In the blank shown in Figs. 3 and 4 the rightliand side flap or extension 6 is made oi ashape different irointhe left hand flap or extension 5,and is not guiniued along its in wardly extending edges. The part 2 will with another to form a chain of envelope as 'snitsble widio is taken on therefore not. be siuelr to this [lap or extension. if on account or other matter be .iiscod in the envelop and the closing flop 2* 1e damped along its gunnned edge ordircjirily and stuck down he envelop will have illc appearance of :1 sealed envelop but; yet he open at one end and subject to the regulotions which alt-P1150111) govern in Great Brit.- nin the tronsinissioi'l of circulars, accounts and othcr nnntfer by holl'penny ost.

in the camstruction illusirotec in Figs. 6 Lo I I tinenvelop is made from two blenks. The blank. which forms the front or address bearing part l and the closing in 2* is i'nt-irely separate from the blank whic '1. forms the back part of the envelop. The latter blank is only formed with. flaps or extensions 5, t; or fl, 7 on three of its sides and these form the sides and bottom flops. To form be other blind; a. long stri of paper of n. (f'fihc pattern of We blank is cm: *lhcrcin and repeated time I tor time. The blanks so out in this strip of caper, .ore as shown in Fig. 11, separated tho one from. no other by lines of perforations or hicisions 3 in a, manner analogous .to fthcpnper of sanitary rolls and the paper is below each line of perforations or incisions 3 rind ot, the edges of the strip'notched or cut away as at ti.

The space inclosd between the line o't perforations or incisions and on innrginurv lino oining the ends of the notches dorms ihe closing flap 2" oi the envelop and The port, of said blonlr which is immediately above the line of perl'oroiions forms, as in the pri r case, n main portion oi'an adjacent cnvelop in the chain, but in this case, forms the front, of the adjncclit member of the series or choinnnd issecored to other portions in such manner that hr the completed series or chains'thc line of lhe perforations or insertions will, as before, coincide with or come on the line or fold constituting the edge of the envelop as will be presently seen. The book of each envelop is formed from an irreguhir polygonal blank (Figs' 6 and b) so shaped that along three of its sides" the side-and bottom flops of the envelop lire formed. The hips 5, ti, in Figs. ti and 7 and the flaps 5, 7 in Figs. 8 and E) are guinnicd on wind. is, when folded {LS shown in Figs. 7 ond 9, their outer surface. The separate t igs. 7 and 9) which form the books velops no when folded laid on and secured to lwi rip of perforated paper ha; oownncdge of eachblank, fold of flap 2 upon cradme of peri'ornticms or incisions 3. mn'elop will then appear as It will be obvious that, envelops in accordance with this invention can .be made in. various shapes and sizes and in various ways.

In Fig. 12', the front or address bearing port 4, the closing flap 2", the side lhips .3, (i or 6 are made in one and as part of a. long strip of aper, the back of the envelop being formed cm a separate blank (Fig. 10) with a flop or extension 7 forming :1. bottom flopv Fig. 13 at D nnd'E shows completed envelops in accordance with this'inodilicnti'on.

.What I claim 1. A series or chain of enrclops capable of separation along lines of perforations. said chain consisting of a number of similar blanks and each envelo) being made up oi two blanks, each said dank comprising 2r front or address bearing part having side flaps adopted to befolded inward toward each other, a closing flop and o. back part, said closing fin hovingits free end dctochnhly connected with that part of the sillinhlanlr which is secured to the side and boi- .rom in s on another bhink to form the back of snot ier envelop of the series or chain and in o manner to bring the linov of perforations into substonbiul coincidence with lllt cdgc oi the envelop.

2. A chain oi cnvclopsjoined togoiln-r but capable of separation along lines of perforations, each envelop being modo- 'up of two blanks and each blank comprising :1 front or address bearing port. side tlnps. a. bottom flap, 1: closing illl]) and :i. bm-h purl, said closing flop having its'l'ree end lclnrllably connected with the portion cons! itut ing the brick part of thoblonk and said buck port forming e. portion of on adjacent onvelop of the chain and sccurcd to the component ports of the adjacent. member of the chain in a manner to bring the line of de taclnnent into substantial coincidence with the edge of the envelop.

3. A chain of envelops copo blc, ol' scpurzv tion a longlines of perforations, suid vnvelops being ouch made up of two blanks, onc oi which comprises the moin portion of one envelop of the chain, a closing hip and :L main portion of on adjacent momber oi tin chain, said closing thip having its free (-nd demchzibly (i()lll]('(jl(tl with the cdgo of tho main portion of said ndjm-cnl mvmber hi ng a. line of perforations substantially \"UilH'iil' ing with the edge of the "nvclop.
